The ultrafiltration membrane is a microporous filtration membrane with consistent pore size specification and the rated pore size range of 0.001-0.02 micron. Solute molecules smaller than the pore size can be screened out by applying proper pressure to one side of the membrane so as to separate particles with molecular weight larger than 500 daltons and particle size larger than 2-20 nanometers. The industrial application of the ultrafiltration membrane is very wide, and the ultrafiltration membrane becomes one of novel chemical unit operations. For use in the separation, concentration, purification of biologics, pharmaceuticals and food industries; also used for terminal treatment devices in blood treatment, wastewater treatment and ultrapure water preparation. In the process of ultrafiltration membrane screening, the pressure difference between two sides of the membrane is used as a driving force, the ultrafiltration membrane is used as a filtering medium, under a certain pressure, when a stock solution flows through the surface of the membrane, a plurality of fine micropores densely distributed on the surface of the ultrafiltration membrane only allow water and small molecular substances to pass through to form a permeate, and substances in the stock solution, the volume of which is greater than the micropore diameter of the surface of the membrane, are intercepted on the liquid inlet side of the membrane to form a concentrated solution, so that the purposes of purification, separation and concentration of the stock solution are realized. About 60 hundred million micropores of 0.01 micron are arranged on the wall of the ultrafiltration membrane filament pipe with the length of each meter, the pore diameter of the ultrafiltration membrane filament pipe only allows water molecules, beneficial mineral substances and trace elements in water to pass through, and the volume of the minimum bacteria is more than 0.02 micron, so that the bacteria, colloid, rust, suspended matters, silt, macromolecular organic matters and the like which are much larger than the volume of the bacteria can be intercepted by the ultrafiltration membrane, and the purification process is realized.
At present, the milipore filter adopts the integral type design more, in case the membrane silk tow of outer membrane shell parcel breaks, perhaps filters for a long time and leads to the pore on the membrane silk wall to be blockked up by a large tracts of land, and that whole milipore filter can lose efficacy promptly, can't continue to carry out the water purification operation, and the cost of whole change can be great.
